According to the compression strength of the stainless steel plate, the oil casing can be divided into different steel grades, such as J55.K55.N80.L80.C90.T95.P110.Q125.V150, etc. The oil casing manufacturer points out the downhole conditions. The steel grade is different for different hole depths. The casing itself is also required to have anti-corrosion function in the natural environment.

Oil casing manufacturers point out that casing can be divided into: soft pipe, face casing, French casing, white edge casing according to the use. Oil and gas pipeline is a large-diameter pipeline that has the function of stabilizing crude oil and vaporized gas wells or wellbores. Casing is placed in the wellbore and reinforced with concrete to prevent wellbore collapse, ensure the fluidity of the drilling sand cycle, and facilitate drilling and excavation.

Wellbore is the key to keep oil and gas wells running normally. Due to different exploration conditions, setting wellbore can be very simple. Supporting effect. Working pressure. Instability and change of ground stress combing act on the pipe body, and put forward better specifications for the quality of casing itself. Due to various reasons, once the casing itself is damaged, it is very likely to cause a decline in the annual output of each well or even damage. L80 oil casing-oil casing is used to support oil. Used for seamless steel pipes. Oil and gas wellbore to ensure the completion of the entire drilling process and make the entire oil well run normally after completion.
